Available to hire
I’m Rujeet Prajapati, a mobile application developer with 3+ years of commercial experience building cross-platform apps using Flutter. I enjoy turning ideas into reliable, user-friendly products—integrating REST APIs, implementing authentication, and adding payment and notification features—while keeping code maintainable with clean architecture and strong state management.
I’m currently pursuing my Master of Information Technology at the University of Technology Sydney, and I’ve also led and shipped production-ready mobile apps that are live on Google Play and the Apple App Store. I like working in Agile teams, collaborating closely with designers and QA, and continuously improving performance and stability so the final experience feels smooth from the user’s perspective.
